This invention relates to improvements in a fiush tank such as is commonly used for domestic purposes.

The main object of this invention is to provide a tank with improved emptying facilities into the bowl with'which it is associated. Heretofore in tanks of this description manually operable lever means for the flush Valve were provided usually in theupper regions of the tank. The ball or siphon valve, as the same is known, usually depended from the end of and which co-operated through a series of arms,- levers and links with the handle member; T

' By means of my construction I have eliminated these features. of a rod extending downwardly therefrom and I operate the same by engaging theifree end thereof by means of a rock arm. Where previously frequentlythe handle means for operating this valve were at the top of the tank for the obvious purpose of avoiding the danger of leaks by enteringthe tank below the water line, by my constructionnomoving parts other than the ball valveitself extend ino the tank. All other parts are disposed in the'adjacent portion of the drain pipe connecting the tank with the bowl.

I realize that tanks'have been previously constructed with valve means operable below the tank, and I do not intend to claim such a feature generally.

The'objects of'iny invention may be concisely stated asembracing, firstly; to provide manually h operable lever means for opening the'valve p'ositioned below the lever of the tank; secondly: to provide such means which are simple in structure, economical to manufacture, durable in character, and consisting 'of relatively few parts; thirdly; the provision of a valve of the character described which is easy to assemble and to disassemble; and fourthly: to provide valve means which may readily be incorporated into a fixture of the old style without disturbing the. existing tank.

Further and other objectswill becomeapparent from a further reading of this specification taken together with the drawing forming part thereof. p

Referring to the drawing wherein like characters represent like parts-throughout the various views; v

Figure 1 is a sectional view in elevation of a valve constructed according to this invention.

Figure 2 is a top plan view of the tank show,- ing the arrangement of the parts.

I aflix the ball valve on the end Figure 3 is a plan view of the mechanism with the valve member removed.

Thetank I3 is connected to the drain pipe I leading to the usual bowl mechanism not shown .in the drawing. The siphon valve I, its associated valve seat'2, and the overflow 3 are of orthodox construction. I provide/a rod .4 .slidable within a stationary tube or bearing 5 positioned at the mouth of the :drain pipe III, on a crossbar 6. A T extension H is provided in the vertical portionof the. drain'pipe. I The mouth of the T extension is sealed by a" relatively heavy flexible disc 8, a lever 9 is fulcrumed through the disc .8.. Theend of theinwardly extending portion ofthe lever 'l is;.adapted to engagethe free .end

-- of-the rod .4 in such manner that downward ma.-

. nipulation of the handle means l8 afiixed at the I end of the outwardly protruding portion of the lever arm 9 raises the rod and brings the siphon valve to open position.

.To avoid disengagement between the rod and its bearing the free end of the former is enlarged. The assembling of the parts is naturally accomplished before the valve and the rod are, securedtogether which may be by any known method. ,In the. drawing the two are-shown threaded together in a well understood manner.

- The, free end of the rod is preferably rounded the, contact face to minimize friction when actuated by the lever during operation.

Since the rock lever is fulcrumed in the flexible disc 8 it must be guarded'against both rotation and lateral displacement either of which may ,tendto disengage-the foot of therod and -manyways which. this can be accomplished; in Figure 3 a verylsimple device for this purpose ably-on a vertical plane to admit a pin 23. rockleverwflus is shown. The nut ll utilized to retain the disc in place is provided with an externally extending flange or body portion. This is drilled-preferprovided with a longitudinal slot 22 through which the pin beforementioned extends, Thus, .both rotation and lateral displacement of the lever is eliminated. For practical reasons it may. befound preferable to dispose :the slot 22 .in such manner that the pin 23 will depend from the tank bottomand extend there- :through, or the objective may be achieved by .linkingtogether loosely the and the adjacentend free end of the rod of the lever in any well known manner.

In constructing the extension of the drain pipe a flange l9 shown in Figure 1 is provided against which the flexible disc 8 abuts, it is held in place of the rock lever.-. There are The p by a nut 11 threaded over the mouth of the T and compressing peripheral portions of the disc to provide a water tight seal. It will be under stood of course that this flange is not essential and that the disc can'be laid. against the mouth of the T and clamped into positionas previously described by a suitable nut. In the drawing the securing together of the rock lever and the disc is shown accomplished by means of a threaded portion on the lever and two opposing nuts with r sections of the flexible disc clamped between them. This type of construction is of course in its simplest form and is capable of'rnany modifications none of which,'however, wouldide-;

part from the spirit ofthis invention.

The conversion of an existing fixture "to operate according to my invention is very simple.

The manner of installing the cross bar 1i carrying the tubular bearing and rod is obvious and need not be explained. A slot is opened in the side wall 'of -.thefldrain pipeflllof -a-" suflicient width to admit therockelever -'l-with relatively :little side 'r-play and of a *sufficientrlength to permit theq-necessary vertical movement of the lever, when it 'is actuated. The -I -like extension 2:

His secured in place by brazing or soldering =or bywany "other method so as \to completely circums'cribe the*slot. 2Wi'th this-construction no additional device for :g ua'rdin'g' against later'al or rotational displacement of the rock'llever is nee-1:;- essary suchxa's in Figure -3 where a slot andiipln arrangement represented by the charaeters=22 and-'23 respectively are sliow'n. If tlie intrudi-ng portion: of the rock lever be 'rectangular in section, and-if thekslot bemade' to provide=a 'relatively snug fit in widthith'ere will be no opportunity forthe lever to either 'rot'ate. or' be displaced laterally.

'It will be readily seen that the construction of the emptying mechanism disclos'ed bymy invention: is infinitely simpler than the mechanism heretofore employed in tanks of thischaract'er, *and that the number of movingr-pa'rts' have' be'en reduced to an =absolute minim'um, namely two 1' elements, the rock a lever "and the ienga'g'ing rod v foration the intruding end whereof engages the free terminus of the valve stem for the purpose of raising the valve to open position and the outwardly extending end provides handle means for its manual manipulation, means for retaining the said lever against rotatable and lateral displacement.

2. A discharge mechanism for a flush tank comprising the usual drain pipe, valve seat and ball valve fitted with a depending stem, a centrally disposed tubular bearing secured to a stationary arm within the said pipe below the seat adapted to support the said valve stem for vertical reciprocation therewithin, a vertical slot in the pipewall substantially opposite the free e'nd'oi the valve'ste'm, a perforated flexible member overlyingthe same and sealing the margins -thereof, a rock lever sealed through the perforavtionand f ulcrumed thereat the intruding portion "whereof extends through the said slot and has =-sectionally rectangular portions adjacent theretowith a -m1nimum*of side clearance with the vertical slot edges and the end whereof 'envides handle means for its manuaL-manlpulatio'n.
